Key Concepts
BST
The Biometric Session Token is minted by your backend. It represents a single biometric operation and carries the operation type and optional user binding.
BRT
The Biometric Result Token is returned after the mobile app completes biometric capture. Your backend verifies this token before treating the operation as valid.
Encrypted Bound User ID
When a user is already enrolled, the server can bind that user to a new session using an encrypted identifier. This keeps the client flow simple while letting the backend preserve user context.
